摘要
论述了NMR法在分子筛研究领域的应用。通过NMR的观测与计算可以确定分子筛骨架的硅铝比,从而分析硅、铝在骨架上的统计分布特征,以及不同结构状态、配位状态和催化机理,进一步对分子筛的合成及其性能的研究提供了重要依据。
This review is concentrated on the NMR applications to the research of zeolites. The NMR is able to determine the framework Si/Al ratio and to analyze the statistical distribution characters of Si,Al atom in the framework of zeolite samples and the various aluminum species presented in zeolites,and provides important basis for researches of the synthesis and the property of zeolites
